SIGNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 533,014, dated January22,1895.

Application and May 27. 1892. Serial Ne.434,635. (N model.)

T0 at whom it may concern: 1

Be it known that LBERNIOE J. NoYEs, of Boston, county of Suffolk, Stateof Massachusetts, have invented an Improvement in 5 Signal-Boxes, ofwhich the following description, in connection 1 with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

Prior to this invention signal boxes have to been provided with localalarms which are sounded when the latch, or knob of the door of the boxis turned, or when a glass fitted in the front of the box is broken, torender aocessible the pull or hook by means of which the signaltransmitter is operated. The person pulling in the alarm is sometimesdeceived by the local alarm, presuming that when sounding, the firealarm or signal is being transmitted, although such boxes have beenplainly marked.

This invention has for its object to provide a signal box containing anysuitable alarm, or signal transmitting apparatus, with a local alarmoperating mechanism adapted to be automatically let off, or operatedwhen the door of the box is opened or a glass fitted in the front of thebox is broken, and to simultaneously let off, or operate the signaltransmitter, so that whenever said local alarm is '0 sounded thetransmitter will be automatically operated, and the signal transmitted,without requiring the person at the box to pull the hook after openingthe door, or after said local alarm has sounded, or during the time itis sounding.

This invention may be carried out in many different ways, but as hereinshown the signal transmitting apparatus, and also the local alarmoperating mechanism, bot-h comprise 40 normally wound motors, which whenreleased, operate to perform their respective duties, yet said motorsmay be normally unwound, and the operating parts so connected togetherthat when the local alarm is operated, the

4 5 signaltransmitting apparatus will also be operated.

Figure 1, shows in front elevation, a signal transmitting apparatus andlocal alarm operating mechanism, and intermediate connection betweenthem, whereby the signal transmitter and local alarmoperating'mechanism,

are both set in operation by the act of opening the door, said partsbeing removed from their inclosing box or case; Fig. 2, a detail of Ithe let off orreleasing device; Fig. 3, a front elevation of the signalbox with the door opened, and Fig. 4t,"a front elevation of the box withthe door closed; Fig. 5, a detail to be referred. to.

The signal transmitting apparatus herein shown consists of a suitableframe, a toothed driving wheel a, mounted on the winding shaft 0.,journaled in said frame and carrying a pawl a which engages a'ratchetwheel disecured to said shaft. I, p

The wheel a, engages a pinion'w, ona shaft carrying a toothed wheel awhich latter en gages a pinion a, secured to a shaft carrying an escapewheel M, with which co-operates the pallet a The signal Wheel a issecured to the shaft carrying'the toothed wheel of, and suitable contactpens 0. are provided which engage Said signal wheel.

The wheel a carries a stop pin a which 7 5 enters a notch in a lockinglever 0. pivoted to the frame at a and carrying a pin a, which enters arecess between the ends of flanges a a", on the wheel a, when the trainis at rest, and which bears upon one or the other flange when the trainis in motion, to thereby keep the locking lever in elevated positionwhile the signal wheel a", is making several revolutions. I

A hook or pull b, is provided, which is adapted to lift one end of thelocking lever (1 to release the train.

This form of signal transmitting apparatus is well known, but in lieu ofit, any other well known form may be employed.

The local alarm mechanism comprises a gong 0, adapted to be struck bythehammers c, on the pallet 0 of the normally wound train, consisting ofthe toothed driving wheel 0 mounted on the winding shaft 0 and con- 5nected therewith by the pawl and ratchet in the usual manner, a pinion cengaged by said toothed wheel 0 a toothed wheel 0 securedto the shaftcarrying said pinion, and the pinion c engaged by said toothed wheel,and secured to a shaft carrying an escape wheel 0 with which said pallet0*,00-0pe12tt68.

A projection c, is secured to the pallet c which is engaged by one armof a bell crank lever 0 see Fig. 2, pivoted at 0 the other arm of saidlever normally bearing against a plate of glass e fitted in the door 0or it may be against the door 0 itself, the glass plate not beingemployed.

A rock shaft d, is mounted in suitable bearings, having at one end ashort arm d, Fig. 5, which terminates justbeneath the end of the lockinglever 0, and has at its other end a short arm (1 which is connected by alink 01 with one arm of the bell crank lever 0 The short arm 01, is madeof suitable length so that when raised to lift the locking lever, thelatter slips off, or is disengaged, and on the end of said arm a smallblock (1" is hinged which permits the arm to pass beneath the lockinglever, thereby resuming its normal position.

The operation is as follows:'VVhen the door 0 is opened, or when theglass plate 0 is broken, the bell crank lever 0 is released, letting offthe local alarm train, which causes the pallet 0 to move the hammers,and strike the gong, and at the same time that said bell crank lever 0is released, the shaft d is rocked moving the locking lever a, andreleasing the signaling train, so that it will be seen that whenever theglass is broken or the door opened and the local alarm operated thesignal will be transmitted. The door 0 is not provided with a lock, butsimply with a latch, which is operated by the handle e, that said doormay be opened without the aid of a key, and hence the box resembles whatis commonly known as a keyless box. The glass plate is inserted in thedoor for the reason that many people can readily understand that to sendan alarm they must break the glass, but as above implied said glassplate may be omitted.

Instead of employing the particular construction shown of intermediatemechanism connecting the two trains, any other form may be employed, andfurthermore instead of connecting the releasing or operating lever ofthe signalingtrain,with the releasingoroperatinglever 0 or with thelocal alarm it may be operated independently by breaking the glass oropening the door. The box is also provided with a door 0 by which accessmay be had thereto, and a slide bolt 0 is arranged on the inner door 0which when moved in one direction passes beneath a pin moving in aslot 0and secured to the link d so that the trains may be held at rest whilethe doors 0 and 0 are opened for inspection, and on the inner door 0 asimilar slide bolt 0 is arranged which when moved in one directionpasses beneath the lever 0 to hold the trains while the door c ,'isbeing opened for inspection, but in lieu of these particular lockingdevices any other equivalent forms may be employed.

I claim- 1. A signal box provided with a door, asignal transmittingapparatus, and a local alarm mechanism in said box the operating leversof both of which are automatically moved to operate their respectiveapparatus and mechanism by opening of said door, substantially asdescribed.

2. In a signal box, a signal transmitting apparatus, and a local alarmmechanism, the operating levers of both of which are simultaneously andautomatically moved by the breaking or removal of a removable frontplate, substantially as described.

3. In a signal box, a signal transmitting mechanism, and a local alarmmechanism, combined with a keyless door for controlling the operatinglovers of said mechanisms, and a locking device to positively lock saidmechanisms when the said door is open for purposes of test, 850.,substantially as described.

4. In a signal box. a signal transmitting mechanism, and a local alarmmechanism, and two inner doors 0 and 0 and locking devices thereon forsaid mechanisms combined with two outer doors a, 0 the latter beingkeyless, and controlling the operating levers of said mechanisms,substantially as described. t

5. In a signal box, a signal transmitting apparatus, and a local alarmoperating mechanism, the operating lever of which is controlled by aremovable front plate, and connections between said local alarmoperating mechanism and the signaling train, whereby the latter isoperated by the forme'r,substantially as described.

6. In a signal box, a signal transmitting mechanism, and a normallywound local alarm mechanism, the releasing lever of which is held by aremovable front plate, and interposed connections between saidmechanisms, whereby the signal transmitting mechanism is operated by thelocal alarm mechanism, substantially as described.

7. In a signal box, a signal transmitting mechanism,and anormally woundlocal alarm mechanism, the releasing lever of which is held by aremovable front plate, the rock shaft d and arms (1, (Z and link dconnecting the arm 61 with the local alarm mechanism, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
